Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a twisted wire separation device. Background Art

[0002] Twisted wire is the most commonly used transmission medium in integrated wiring projects. Twisted wire is usually composed of two insulated copper wires twisted together at a certain density to reduce the degree of signal interference. One or more pairs of wires twisted together constitute a twisted wire cable.

[0003] When a twisted wire cable is connected to a plug-in terminal, the wires twisted together at the end need to be separated and straightened. In the prior art, the twisted wire separation and straightening processes are mostly completed manually. A small number of twisted wire separation devices also need to handle the twisted wire separation process and straightening process separately, and the twisted wire separation efficiency is low. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a stranded wire separation device to improve the separation efficiency of the stranded wires.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0011] Furthermore, it also includes a second tank chain, one end of the second tank chain is connected to the sliding bottom plate, and one end of the second tank chain away from the sliding bottom plate is connected to the wire twisting bottom plate.

[0012] Furthermore, it also includes a wire clamping mechanism arranged on the sliding base plate, and the wire clamping mechanism includes a wire clamping cylinder, a wire clamping mounting seat arranged on the wire clamping cylinder, and a clamping claw assembly connecting the wire clamping cylinder and the wire clamping mounting seat at the same time.

Figure 2 A three-dimensional structural schematic diagram of the lifting mechanism 4 and the wire twisting mechanism 6 in the twisted wire separation device provided in an embodiment of the utility model is shown. Figure 3 FIG. 5 shows a three-dimensional structural diagram of the reverse twisting mechanism 5 in the twisted wire separation device provided by the embodiment of the utility model. Figure 1 , Figure 2 and Figure 3 The twisting wire separation device includes a sliding base plate 2, on which a wire-rubbing base plate 3 is slidably connected; a lifting mechanism 4, which is arranged on the wire-rubbing base plate 3, and two wire-rubbing slide rails 62 are connected to the wire-rubbing base plate 3 through the lifting mechanism 4; a wire-rubbing mechanism 6, which includes an upper rubbing plate 63 and a lower rubbing plate 65 arranged vertically, and the upper rubbing plate 63 and the lower rubbing plate 65 are respectively connected to the same direction of the wire-rubbing slide rails 62, and the wire-rubbing slide rails 62 are perpendicular to the sliding direction of the wire-rubbing base plate 3; an anti-twisting mechanism 5, which is arranged on the wire-rubbing base plate 3, and includes a rotating plate 52, an upper connecting rod 53 that simultaneously connects the upper rubbing plate 63 and the upper part of the rotating plate 52, and a lower connecting rod 54 that simultaneously connects the lower rubbing plate 65 and the lower part of the rotating plate 52. Specifically, the upper connecting rod 53 and the lower connecting rod 54 are respectively connected to the rotating plate 52 through the driving joint bearing 531, and are respectively connected to the upper rubbing plate 63 and the lower rubbing plate 65 through the wire-rubbing joint bearing 532. The upper rubbing plate 63 is connected to the upper adjustment block 44 through the connecting plate 61, and the lower rubbing plate 65 is connected to the lower adjustment block 45 through the connecting plate 61. After the lifting mechanism 4 drives the upper rubbing plate 63 and the lower rubbing plate 65 to close and clamp the wire, the rotating plate 52 in the reverse twisting mechanism 5 is rotated to drive the upper connecting rod 53 and the lower connecting rod 54, and then drive the upper rubbing plate 63 and the lower rubbing plate 65 to move in the opposite direction, and reverse twist the stranded wire clamped by the upper rubbing plate 63 and the lower rubbing plate 65. At the same time, the wire rubbing bottom plate 3 slides relative to the sliding bottom plate 2, and the wire rubbing bottom plate 3 is slid away from the stranded wire, which can drive the upper rubbing plate 63 and the lower rubbing plate 65 to straighten and separate the smaller ones. The separation and straightening of the stranded wire are integrated into one device, and the separation and straightening are combined into one process and carried out simultaneously, which greatly improves the separation efficiency of the stranded wire.

The lifting mechanism 4 also includes a vertical plate 41, and the vertical plate 41 is provided with a lifting slide rail 42, and the upper adjustment block 44 and the lower adjustment block 45 are connected to the lifting slide rail 42. The lifting mechanism 4 also includes a lifting motor 46, and the lifting motor 46 is connected to the positive and negative threaded rod 43 through a synchronous belt 47. The synchronous belt 47 can effectively alleviate the load impact and reduce the damage to the stranded wire when the upper rubbing plate 63 and the lower rubbing plate 65 separate the stranded wire.

[0032] Please refer to Figure 2 The surface opposite to the upper rubbing plate 63 and the lower rubbing plate 65 is a rough surface 64. The upper rubbing plate 63 and the lower rubbing plate 65 are made of polyurethane. The polyurethane on the rough surface rubs the strands and protects the insulating surface. The friction between the rough surface 64 and the strands is greater, ensuring that the upper rubbing plate 63 and the lower rubbing plate 65 separate the strands when they are reversed. A waste tray 31 is also provided on the wire rubbing bottom plate 3. The waste tray 31, the upper rubbing plate 63 and the lower rubbing plate 65 are in the same straight line to collect the waste scraps peeled off during the reverse twisting process.

[0033] The specific structures of the base 1, the first tank chain 8 and the second tank chain 9 are described below:

[0034] Please refer to Figure 1 , and also includes a base 1, and a sliding base plate 2 is slidably connected to the base 1. The sliding base plate 2 is slidably connected to the base 1 through a secondary guide rail slider 11, so as to facilitate the overall movement of the positions of the lifting mechanism 4, the reverse twisting mechanism 5, the wire twisting mechanism 6 and the wire clamping mechanism 7 to adapt to different working conditions.

[0035] Please refer to Figure 1 , and further includes a first tank chain 8, one end of the first tank chain 8 is connected to the base 1, and the end of the first tank chain 8 away from the base 1 is connected to the sliding base plate 2. A first support plate 81 is provided on the base 1, and a second support plate 91 is provided on the sliding base plate 2. The first tank chain 8 connects the first support plate 81 and the second support plate 91 to protect the cables connecting the second guide rail slider and the primary guide rail slider 21. It also includes a second tank chain 9, one end of the second tank chain 9 is connected to the sliding base plate 2, and the end of the second tank chain 9 away from the sliding base plate 2 is connected to the wire twisting base plate 3. The second tank chain 9 is connected to the second support plate 91 below, and the second tank chain 9 is connected to the wire twisting base plate 3 above, so as to protect the cables connecting the lifting motor 46 and the reverse twisting drive assembly 51.

[0036] The specific structure of the clamping mechanism 7 is described below:

[0037] Figure 4 The three-dimensional structure diagram of the main wire clamping mechanism 7 of the stranded wire separation device provided by the embodiment of the utility model is shown. Figure 1 and Figure 4 , and further includes a wire clamping mechanism 7 disposed on the sliding bottom plate 2, the wire clamping mechanism 7 including a wire clamping cylinder 71, a wire clamping mounting seat 72 disposed on the wire clamping cylinder 71, and a clamping claw assembly 73 simultaneously connected to the wire clamping cylinder 71 and the wire clamping mounting seat 72. The clamping claw assembly 73 clamps and fixes the stranded wire to prevent the stranded wire from moving when it is reversely twisted and separated by the twisting mechanism 6, thereby ensuring the quality of the stranded wire.

[0038] Figure 5 The internal structure diagram of the wire clamping mechanism 7 in the wire separation device provided by the embodiment of the utility model is shown. Figure 5 The clamping jaw assembly 73 includes a left clamping jaw 733 and a right clamping jaw 734, which are respectively rotatably connected to the clamping wire mounting seat 72; the output end of the clamping wire cylinder 71 is connected to the left clamping jaw 733 through the left connecting rod 731, and is connected to the right clamping jaw 734 through the right connecting rod 732. The output end of the clamping wire cylinder 71 extends, the left connecting rod 731 pushes the left clamping jaw 733 to rotate around the clamping wire mounting seat 72 around its rotating connection part 735, and the right connecting rod 732 pushes the right clamping jaw 734 to rotate around the clamping wire mounting seat 72 around its rotating connection part 735, until the clamping parts 736 on the left clamping jaw 733 and the right clamping jaw 734 are closed to clamp and fix the stranded wire.

[0039] Please refer to Figure 1 , Figure 2 and Figure 4 A wire support plate is also provided on the wire clamp mounting seat 72. The distal end of the wire support plate is flush with the middle position of the upper rubbing plate 63 and the lower rubbing plate 65. Before the clamping claw assembly 73 clamps the stranded wire, the clamped wire is first supported by the wire support plate to quickly locate the upper and lower positions of the stranded wire.

[0040] The specific working process of the utility model is as follows:

[0041] When separating the stranded wires, the sliding base plate 2 slides to a predetermined position along the base 1 according to the feeding position of the stranded wires, and the feeding device (not shown in the figure) places the stranded wires stripped of the outer insulation layer on the support plate, and the clamping cylinder 71 is started to drive the left clamping jaw 733 and the right clamping jaw 734 to rotate and close to clamp the stranded wires. The wire-rubbing base plate 3 slides along the sliding base plate 2 until the exposed stranded wires are located between the upper rubbing plate 63 and the lower rubbing plate 65. The lifting mechanism 4 is driven to drive the positive and negative threaded rod 43 to rotate forward, and the upper adjustment block 44 and the lower adjustment block 45 fixed on the positive and negative threaded rod 43 are close until the upper rubbing plate 63 on the upper adjustment block 44 and the lower rubbing plate 65 on the lower adjustment block 45 clamp the stranded wires. The reverse twisting drive assembly 51 drives the rotating plate 52 to rotate in the reverse twisting direction, driving the upper connecting rod 53 and the lower connecting rod 54 to move horizontally, and then drives the upper rubbing plate 63 and the lower rubbing plate 65 connected to the upper connecting rod 53 and the lower connecting rod 54 to move horizontally, and reverse twist the stranded wires. This reverse twisting action can be performed multiple times until the strands are completely separated. In the process of the upper rubbing plate 63 and the lower rubbing plate 65 moving horizontally, the rubbing plate slides along the sliding base plate 2 in the direction away from the strands to straighten the separated strands while reverse twisting the separated strands.

[0042] It can be seen that in the above-mentioned stranded wire separation device, the upper rubbing plate 63 and the lower rubbing plate 65 are arranged on the lifting mechanism 4 and are respectively connected to the wire rubbing slide rail 62. After the lifting mechanism 4 drives the upper rubbing plate 63 and the lower rubbing plate 65 to close and clamp the wire, the rotating plate 52 in the reverse twisting mechanism 5 is rotated, which can drive the upper connecting rod 53 and the lower connecting rod 54, and then drive the upper rubbing plate 63 and the lower rubbing plate 65 to move in the opposite direction, and reverse twist the stranded wire clamped by the upper rubbing plate 63 and the lower rubbing plate 65. At the same time, the wire rubbing bottom plate 3 slides relative to the sliding bottom plate 2, and the wire rubbing bottom plate 3 is slid away from the stranded wire, which can drive the upper rubbing plate 63 and the lower rubbing plate 65 to straighten the separated stranded wire. The separation and straightening of the stranded wire are integrated into one device, and the separation and straightening are combined into one process and carried out simultaneously, which greatly improves the separation efficiency of the stranded wire.

[0043] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
